CALENDAR.

SPECIFICATION forming part of Letters 'Patent No. 392.327, dated November 6,'1888.

Application filed April 3, 1888. Serial No. 269,491. (No n iodcl.)

To all whom, t 71ml/ concern,.-

.Be it known that I, WILLIAM W. HAAs, a cltizen of the United States, residing at Newton, in the county of Harvey and State of Kansas, have invented new and useful 'Improvements in Calendars, of which the following is a specification.

My invention relates to improvements in calendars; and it has for its objects to provide [o a perpetual calendar in which the adjustment drawings, wherein- Figure 1 is a front view of the improved calendar adjusted for March, 1888. Fig. 2 is a detail vertical sectional view through the slide or tablet.

Referring to the drawings, the card or body of the calendar A may be of any desired shape, (preferably rectangulan) and may be ornamented in any preferred manner, and itis provided near its lower end with the horizontal slot B. The table O contains the names ofthe days of the week lfrom Sunday to Friday of the following week,(thirteen days,) and they are arranged in a horizontal series parallel with the slot B andjustabove the same. Be-

low the slot B a similar'table is arranged, the

only difference being that the names in this table extend from Monday to Saturday of the following week, (thirteen days.)

E representsa slide or tablet, which bears 4o against the face of the card or calendar between the daytables O D, and is provided on its rear side with a button, F, which bears against the rear side of the card or calendar vand has a shank slidingin the slot B. On this slide or tablet are arranged the days of the month in horizontal series, seven days being arranged in each series. This slide may be adjusted at any part of the slot B to bring the figure 1 thereon under any day of the week 5o from Sunday to the following Saturday, the remaining six figures in the horizontal series falling under the six week-days following the one indicated by the iirst ligure. (The lower table, D, being arranged similarly to the upper table, with the exception mentioned above, the days of the week may also be indicated thereon.)

Above the upper day-table and to the left of the card A is arranged a year-column, G, containing the following years: 1888, 1889, 1890, 1891, 1892, 1894., and 1898, and after each of the said years is arranged a series of years, which may be extended at will. The years given in full on the left are sample years, and any year outside of this series may be compared with one of these. For instance, 1882, 1898, and 1899 are identical with the year 1888, and the calendar of one may be taken for the others. The saine is true of the years 1894, 1877, 1883, and 1900, and also of 1891, 1874, 1880, and 1885. This column of years constitutes a table to which any year, either in the past or future, maybe referred.

Opposite the years above mentioned and over the day-tables are arranged the names of the mouths in the following manner: Over .Sunday of the upper day-table are arranged the names of the months whose lirst days come on Sunday. Over Monday are arranged the names of the months whose first days come o n Monday, and so on through the entire table. For instance, in 1888 over Sunday are arranged January and October; over Monday is arranged May; over Tuesday is August; over Wednesday are February, March, and November; over Thursday is June; over Friday are September and December, and over Saturday are April and July. The months following the other years are similarly but not identically arranged.

The operation of the calendar is as follows: On the lirst day of each `month adjust the iigure 1 of the slide or tablet under the required month which appears opposite the required year. In ease of leap-years, the upper daytable will indicate the days of the week for the first two Inonths,(Jannary and February,) after which the lower table must be used throughout the year.

Under the lower day-table are arranged the directions for operating the calendar, and itv will be apparent that it is so simple as to be readily understood.

Having thus described my invention, I claim- 1. In' a calendar, the day-table C, the year- IOC) column, the months arranged opposite the ranged substantially as and for the purpose Io years and above the day-table, and the slide speeied. having the days of the month, substantial] y as In testimony that I claim the foregoing as my specified. l own I have hereto affixed my signature in pres- 2.
